SIM card slot

If your computer has a wireless WAN feature, it might require a Subscriber Identification Module (SIM) card to establish wireless WAN connections. Depending on the country of delivery, the SIM card might already be installed in the SIM card slot.

Battery

Use your computer with battery power whenever ac power is unavailable.

Docking station connector

Connect your computer to a supported port replicator or docking station through this connector to extend the computer capabilities when you are in your office or at home. For more information about the supported docking stations, see “ThinkPad port replicators and docking stations” on page 102.

Memory-upgrade slot

You can increase the amount of memory in your computer by installing a memory module in the memory-upgrade slot. Memory modules are available as options from Lenovo.

For more information, see “Replacing and installing a memory module” on page 82.

Hard disk drive or solid-state drive

Depending on the model, your computer might have a large-capacity, customer-upgradable hard disk drive that can meet a variety of storage demands.

If you wish, you can purchase another hard disk drive and install it in the Serial Ultrabay Enhanced bay. For details, see “Installing a secondary hard disk drive” on page 96.

Some models are equipped with a solid-state drive for data storage, making your computer lighter, smaller, and faster.
